Do you know what the fox says? Based on the hugely popular YouTube video with more than 200 million views, this picture book is packed full of foxy fun. Dog goes woof. Cat goes meow. Bird goes tweet and mouse goes squeak... But what does the fox say? The lyrics of Ylvis's YouTube sensation "The Fox (What Does the Fox Say?)" meet Svein Nyhus's playful illustrations in this irresistibly entertaining read-aloud picture book.
